INSTALLATION OF THIS ADAPTOR SHALL BE IN ACCORDANCE WITH THE REQUIREMENTS OF THE AUTHORITIES HAVING JURISDICTION

Refer also to HOYME Installation Instructions: Combustion Inlet Air Control Damper, Series HOM-SF1 ans SF2; Replacement/Ventilation Air Control Damper, Series - HAC/MAC-0x11-SPC, HAC/MAC-0x10-SPO.

RADP-0242-S10A

4” x 5” x 2 ½” (101 x 127 x 64 mm)

This interface Adaptor RADP-0241-S10A is an interlocking control device to safely supply fresh air for a dryer/damper/furnace combination. The Adaptor has a manual red light switch that, when turned on, the fresh air damper opens proving its position prior to gas dryer operation (Interlocked).

This Adaptor may be interlocked to dampers:-HOM-0x11-SF1-HOM-0x12-SF2,secondary circuit;-HAC/MAC-0x11-SPC;-HAC/MAC-0x10-SPO;

This Adaptor may also be interconnected to simultaneously turn on a Furnace Circulation Fan and to open an HAC replacement air damper, if used, on a furnace return plenum. HAC Damper may also open during furnace firing. Damper(s) remain open until the red light switch is manually turned off.

Fitness of this Adaptor/Damper combination to satisfy air supply requirements for fuel fired appliances during operation of the interconnected exhaust fan(s) shall be investigated by the enforcing authorities.

Air intake duct installation shall be in accordance with: In Canada - CAN/CSA B149 & B139; In the USA -ANSI NFPA 2006, ANSI Z223.1 and/or local codes including local codes relating to ventilation air duct installation.

d) Turn on the electric power to the Damper causing the damper to close.

e) Plug the Adaptor cord into the 120Vac outlet.

f) Plug the dryer cord into the ‘GAS DRYER’ side of the Adaptor Receptacle.

g) Turn on the Adaptor Red Light Switch. The Fresh Air Damper(s) will open and the Gas Dryer is ready to be set for its operation.

h) After the drying cycle is complete, turn the Red Light Switch off and the damper will close.

2. Damper HOM-0x12-SF2 used for the DUAL PURPOSE of supplying combustion air to both a heating appliance and to a Gas Dryer:

Note: Confirm HOM-SF2 damper is properly working with primary furnace before connecting to the Gas Dryer. Refer to the Installation Instructions supplied with the Combustion Air Control Damper to confirm its proper operation.

a) Mount the Adaptor next to the Gas Dryer for ease of Red Light Switch operation and near the 120Vac outlet that was used for the dryer.

b) Turn off the appliance power to the HOM-0x12-SF2 Combustion Air Damper.

c) Run a 5C-18Ga. electric wire along the gas line from the Heating Appliance electrical circuit to the RADP-0242-S10A Adaptor.

d) Connect the secondary circuit of the HOM Combustion Air Damper, the Adaptor and the Heating Appliance as follows:

b) Turn on the Adaptor Red Light Switch. The air supply damper will open, the furnace circulation fan will run and the Gas Dryer is ready to be programmed for its operation.

c) After the Gas Dryer has finished its cycle, turn the Adaptor Red Light Switch off. The furnace circulation fan will stop and the air supply Damper will close.

4. A REPLACEMENT AIR CONTROL DAMPER HAC-0x10-OPO/PC on a fresh air duct leading into the return plenum may be used provided it is interconnected to open simultaneously with the furnace circulation fan when the Red Light Switch is turned on:

a) For the HAC damper Power Open type:

- Connect one HAC damper wire to ‘C’ or ground screw on the furnace- Connect the other HAC damper wire to Adaptor #5.

b) For the HAC damper Power Close type:

- Connect one HAC damper wire to ‘C’ or a ground screw on the furnace- Connect the other HAC damper wire to Adaptor #4.

5. If REPLACEMENT AIR CONTROL DAMPER HAC placed on a fresh air duct leading into the return plenum is required to open DURING FURNACE FIRING:

a) Use 18 ga. wire and connect Adaptor #9 to the 'W' terminal of the furnace.
